Thousands of people in Sheffield are giving up alcohol for the Dry January initiative.
Last year, more than 17,000 people signed up to take part in the scheme, which encourages people to take a month off from drinking alcohol.
The scheme is being backed by Sheffield GPs, who have said it is not too late for other people to sign up.
Dr Marion Sloan, a Sheffield GP and one of the Clinical Leads at NHS Sheffield Clinical Commissioning Group, said: “Many of us enjoy an alcoholic drink every now and again but there are significant health risks associated with excess alcohol consumption.
“Alcohol misuse can lead to a number of harmful physical and psychological effects, such as alcohol poisoning, cirrhosis of the liver, inability to work and socialise and destructive behaviours, such as drink-driving. Your risk of developing problems increases with the amount of alcohol you drink.
“After the excesses of Christmas, January is the perfect time for us all to take some time off from alcohol. It’s also a great way to lose weight, feel better, save money and make a difference to your overall health.”
